What scale is used here?

I know the minor scale relatively well, I'm not sure what kind of scale August Burns Red is using here. I'm writing some songs and am looking for something new to help me, the melody of this song is very inspiring and I want to create music like it. Based off this tab isn't it possible to find the root scale used? Any helps is appreciated, thanks.

Figure one is what you'd call a "Lydian mode".Figure two is just a regular minor scale.

A lydian mode is a scale that can be thought of in two ways.The first way is the most easy way to think of it: a regular major scale with a raised or sharp 4th degree.So a normal C major scale would be C D E F G A B CC Lydian would look like C D E F# G A B CF is the 4th degree of the C major scale, so to make it Lydian, you raise the 4th degree.

The second way to think of it is that the major scale is comprised of things called "modes". A mode contains the same notes as a major scale, but starts on a different note.So lets take the scale C major again. the 1st degree of the scale is C, the second is D, the third is E and so on. If you create a scale starting on any of these notes, it will give a different sound.

The Lydian scale derives from the 4th degree of a major scale, so in C major, we would be going F to F. This looks like F G A B C D E F. The normal F major scale has a Bb, but you'll notice that the F lydian scale has a B natural, which accounts for the sharp 4 needed in a Lydian scale.
